Thermally insulated pipe for conveying fluids.

摘要

The invention comprises a thermally insulating structure around a central or tube core. It comprises, around the said internal or tube core (1) a plurality of annular partitions (3) distributed along the length of the said core and integral with this, an insulating material (6) filling the annular chambers let in between the front faces of the successive partitions and the outer covering (2) of the inner core, and a continuous, extruded, outer sheath (4) which is concentric with the said core and integral with the peripheral surfaces of the said annular partitions and of the said insulating material. <IMAGE>
